Your sequence
-8, 16/3, -32/9, 64/27
is a geometric sequence with first term -8 and common ratio
(16/3)/(-8) = (-32/9)/(16/3) = -2/3
The general term an of a geometric sequence with first term a1 and ratio r is given by
an = a1·r^(n-1)
For your sequence, this is
an = -8·(-2/3)^(n-1)
If you're going to use technology (Brainly) to solve this problem, you might find you get a quicker answer using the technology of your graphing calculator.
It is often convenient to cast the problem in the form f(θ) = 0. You can do that by adding 1 to both sides of the equation.
Answer:
10 and 11
Step-by-step explanation:
Let the first integer be x.
Then the next one, since it's consecutive, must be (x+1).
The two equals 21. Thus:
Combine like terms:
Subtract 1 from both sides:
Divide both sides by 2:
So, the first integer is 10.
And the second integer is 10+1=11.

Answer:
B/2
Step-by-step explanation:
The table mentions that the time actually starts from the end of the first month, so it cannot be graph one, which starts from 0.
Also, we can see that the values are decreasing over time, meaning it cannot be graph 3, which shows an increase.
thus, we settle the Answer as Graph 2, which satisfies all the needs.
Hope this helps.
